Hi all, I'd like to discuss a small KIP to make server-side rack-aware assignment opt-in.
Rack-aware assignment only helps when consumers fetch from followers and the replicas of a partition do not cover every rack, yet the group coordinator pays for it for every group today. The KIP adds a broker configuration, off by default, to enable it for consumer groups. https://cwiki.apache.org/confluence/x/d6fwGg Best, David
